I've used samsung drivers package that installs scanner and printer drivers in one shot
but reading INSTALL it asked for cups, ghostscript and sane.

Now that's all configured I give a try at xsane
and it came-up with a warning window: "You try to run XSane as ROOT, that really is DANGEROUS!"
than I try as a user but it show again!

Why there is such configuration?

everyone can lunch xsane, that and everyone do that
make the process run with effective uid=0

I'm posting here again but maybe a new post is needed fot this ossevation: pleace help!

I've found an inconsistency in the man page for useradd command and how it work for me.
Man page says that defualt gid for the new account is 1 if -g option is not used.
I've created 3 account with the handbook procedure( http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=11 ) and a new group has been added for each user.
These are my group and passwd:

I think this can be related with the xsane problem cause of the bin group ID is 1.

But why we must have all these groups?_________________They produce notes of any size as their own properties askng interests also.This is seignorage and goes to privates banks(FED, BCE).You don't have to pay to use $$,you can simply use your notes recovering monetary sovereignty.Public debt is not right!
